    <p>I've got such query:</p> <pre><code>$sql = "UPDATE test_accs SET acc_owner = '$owner_id', acc_policy_version = '$version', acc_policy_last_update = '$approved', acc_policy_next_update = '$renewed' WHERE acc_id = '1'"; </code></pre> <p>Now, all of these values on the web folmular are optional, one can set one of these values, two, or so. Now, after I submit the form, it goes in the query like that:</p> <pre><code>UPDATE test_accs SET acc_owner = '2', acc_policy_version = '1.2', acc_policy_last_update = '2012-12-19', acc_policy_next_update = '2012-12-18' WHERE acc_id = '1' </code></pre> <p>It works only when I submit all values from the form. Can you please show me how could it work even if not all the values has been sent, just for example one of them?</p> <p>When I set one value (f.ex. policy version), it looks like that:</p> <pre><code>UPDATE test_accs SET acc_owner = '', acc_policy_version = '1.2', acc_policy_last_update = '', acc_policy_next_update = '' WHERE acc_id = '1' </code></pre> <p>and it isn't working.</p> <p>It might be possible cause of the acc_owner table values?</p> <pre><code>#1366 - Incorrect integer value: '' for column 'acc_owner' at row 1 </code></pre> <p>Thanks in advice.</p> <p>Form:</p> <pre><code>echo '&lt;td&gt;Change owner: &lt;select name="owner_id" onchange="showUser(this.value)" style="font-size:9px"&gt;&lt;option value=""&gt;Select a person:&lt;/option&gt;'; while($owners = mysql_fetch_array($owners_query)) { echo '&lt;option value="'.$owners['id'].'"&gt;'.$owners['surname'].' '.$owners['name'].'&lt;/option&gt;&lt;/h2&gt;'; } echo '&lt;/select&gt;&lt;/td&gt;'; echo "&lt;td&gt;&lt;input name='version' style='width:50px;text-align:center' placeholder='0.0' /&gt;&lt;/td&gt;"; echo "&lt;td&gt;&lt;input name='approved' class='datepicker_all' readonly='readonly' style='text-align:center' placeholder='1999-01-01' /&gt;&lt;/td&gt;"; echo "&lt;td&gt;&lt;input name='renewed' class='datepicker_all' readonly='readonly' style='text-align:center' placeholder='1999-01-01' /&gt;&lt;/td&gt;"; </code></pre>

    3. COno, not your form... the php that collects the values from your form. If I understand you, you want to update rows and exclude the fields left blank on the form?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
